This research analyses Generative Artificial Intelligence (GenAI) application as an tools within the field of character design by considering visual communication design principles and cognitive psychology. Translating the results describes the research focus as being on how well AI can synthesize traditional characters bios (like Grappler) or genres (like: Rushdown), and visual languages as seen between fighting games like Street Fighter and Guilty Gear. The study covers the capacity of AI systems to mimic statistical averages (Prototype Theory) and how this process affects the design's SNR through analyses conducted via case studies. Experimental prompt studies illustrate the algorithmic success of AI at constituting anatomical mass (square forms) and dynamic vectors (triangular forms), but also how maximalis” detail density threatens functional readability by placing increased cognitive load on the player. According to the research, AI is not so much a design replacement as an evolution of the designer’s role from operational labor (digital painting) to strategic visual curation and semantic governance. A future design paradigm is re-defined as a hybrid collaborative model between the AI’s computational breadth and human contextual intuition & hierarchy management. This confirms a prediction of this study: the most pressing challenge to be met by the next generation of designers will be to keep their style signature in a world susceptible to algorithmic homogeneity.
